Documented Uses

Used as hybridizing agent for wheat (plant growth regulator); [Merck Index] A plant growth regulator used in the production of hybrid wheat seed; Only used by specially-trained seed company personnel; [Reference #1]
Plant growth regulator for use in the production of hybrid wheat seed. Clofencet is registered for use on wheat as a seed crop and on rotational crops of the cereal group (except rice, wild rice, sweet corn and wheat) and soybeans.
It is estimated that at maximum market saturation, clofencet will be applied to less than 300,000 acres of the total US wheat acreage (less than or equal to 0.5%). Initial use is projected on 12,000 acres or 0.02% of the total US wheat acreage.
